Because of its great sensibility and its wide range of detection, it is intentionally obstacled in some directions to avoid useless measurements. He can link his personal device via Bluetooth connection (a Bluetooth module is connected to Arduino).Ī PIR sensor detects a movement if the user takes his medicine and gives a feedback of the correct work of the dispenser. The user can also set his therapy and the dispensing time through an App for smarphone. Two Buttons and a RGB Liquid Crystal Display permit to the user to interact with the dispenser. The RTC module runs on a battery and can keep track of the time even if we reprogram the microcontroller or disconnect the main power. To notify to the user that it is time to take his therapy we built an alarm with a Buzzer and a Real-Time Clock. To be sure that pills are always in good conditions, a Humidity and Temperature sensors measures costantly the temperature and humidity inside the dispenser. Using a motor shield, we increase the number of free pins. It contains 4 H-Bridge that allow to control both direction and speed of the motors. Moreover, they have excellent repeatability and return to the same location accurately.Ī Motor Shield drives the two stepper motors. The motor is also a position trasducer: sensors of position and speed are not required. Stepper Motors are stables, can drive a wide range of frictional and inertial loads, don't need feedback. For this reason, we decide to use two stepper motors. The mechanisms of dispensing and of refilling require great precision and little movements of the wheels that contain the pills. 1 piece of plexiglass for laser cutting.2 x Poussoir Mtallique Carr+Avec Capuchon Bleu.Set of AWG Breadboard Jumper Wires One Pin.40 Pins 30 cm Male To Female Jumper Wire.SHAFT COUPLER POLOLU-1203 UNIVERSAL MOUNTIBG HUB.OfficeTree® 20 Mini magnets OfficeTree® 20 6x2 mm.AZDelivery PAQUET HD447, 2X16 characters + l'interface I2C.
